A: My personal preference is not to use food at all. When I have trained dogs for obedience, I have always used the verbal praise-reward method. It works well, especially with some dogs who are not motivated by food rewards.
Many people do use treat-based training with success, but I don't recommend offering table scraps as the treat. Giving a dog people food—in training or just as a general reward—may give the dog the idea that such food is fair game. It might encourage your pet to steal food from the table or from people, especially kids or guests.
In addition, many human foods can be toxic to dogs. These include chocolate, grapes, raisins, macadamia nuts, and xylitol (a sweetener often used in gum, candy, and baked goods).
As an alternative to table scraps, you could train your dog with snacks that are tasty, low in fat, and commercially prepared for training. But keep in mind that soft chew snacks may be high in sugar, which is bad for dental health. When shopping for treats, read package labels and choose premium varieties that list meat as the first ingredient.
Use only small amounts for training purposes—treats should not interfere with the consistency of a normal diet or greatly affect the caloric intake for the size and age of the dog. The training sessions should be short in length and repeated several times throughout the day. For young dogs, the training period should be no longer than five minutes.
Finally, the most important training tip is to keep it positive. If you're getting frustrated with your puppy's naturally short attention span, take a break. Strive to end the session on a positive note so your pet will be eager for the next time.

Found in the blood and in the fluid that surrounds cells, sodium maintains the cellular environment and prevents cells from swelling or dehydrating. Sodium is also important for maintaining proper nerve and muscle cell function.
Meat, poultry, fish, and eggs are good sources of sodium.
Sodium also might be included in commercial pet foods in the form of table salt (sometimes listed on the ingredient panel as salt). Salt is an important palatant for animals, as well as for people.
The Association of American Feed Control Officials recommends that dry dog foods contain at least 0.3% sodium for both maintenance and to support normal growth and development. This is the minimum recommended levels.
While high sodium intake might cause increased thirst and water consumption, the extra sodium is excreted in the urine of dogs. Healthy dogs are able to consume diets with higher sodium levels than those found in most commercial pet foods without increased blood pressure or gain in body water.
Therefore, the sodium level in commercial pet foods is not a cause for concern in healthy animals.

A veterinarian might recommend decreasing a dog's sodium intake if the animal has some types of kidney, liver, or heart disease, in order to help decrease high blood pressure or the accumulation of excessive body fluid.
Although older dogs might be more likely to develop these diseases, healthy older dogs do not require a low- or reduced-sodium diet.
The sodium level in our dog foods is appropriate for a healthy dog. The sodium content in these foods is balanced in proper proportions with energy, other minerals, vitamins, fats, proteins, and carbohydrates.
